DISPLAY DEVICE.

Application iled December 2, 1,927. Serial No. 237,279.

. This invention relates to improvements in display devices.v the present lnvention being an improvement uponthe display device disclosed in applications Serial No. 152,950 and -the tan used without the device.

ilnoti'ier ohjectot the invention is the pro vision ot means for providing adriving conrulclion hetwecn the tan motor and the device, ii'herebv the speed oi' operation ot the device may he controlled. or the tan may `he used with the d isplav device idle and without rernoval from lthe tan.

ll'ith the above yand other objects in view,

' theinvention ini-ther includes the following lift novel tentures and details ot construction, to he hereinafter 'more iully described, illus tratt-d in the accompanying drawings and pointed out in the appended claims.

in the drawings zligure l is an elevation showing the invention applied to an electric ian. l

lligjure 2 is an enlarged fragmentary sec tional view illustratiny,- the driving connection between the device and the vtan motor.

liigure 3 is a section taken substantially on the line SW3 ot Figure 2 with the gearing arranged to operate the display device.

liie'ure el; is a similar view showin;` the position et the gearing when the display device is inactive.

liigrure 6 is a. sectional view taken axially of the countershatt and showinga the manner of 'en'iovahly attachin the display device to the is an elevation et the display de liiggjure "l a soctiontalten substantially on the line -l of litigare 6.

liclferrinc; to the drawings in detail where in like characters ot re'tcrence denote correspond 15,2 parts. the reference character 10 in diente the housing); oi' the tan motor which is mounted upon a pedestal 11, while the motor shalt is shown at l2, the hlades 13 oit the tau heine; shown as operating within a guard. 14.-.

' lhe invention resides in the means 'for mounting and driving the display device and comprises :1 countershutt l5 whose inner end is mounted in a. bearing 1G carried by the housing1 l() and whose outer end is mounted in a hearing` 1T which is carried by a casing'l, the latterheing secured to the housing l() hy means ot screws 19. This casing?,r is posi tionerl over one end of the housing l0 and the shatt 15 extends through this casing and has mounted thereon an insulating block 20. The bloc t 0 is provided with spaced sockets 21 andlocated at the inner ends ot these sockets are electric: contacts 22. The contacts are 'in electrical connection with collector` rings 225 which are mounted upon the shaft 15 and 'l'or this'purpose, conductors 24: extend through the shaft 15. the latter being hollow at its outer end. rthe collector rings 23 are engaged hy brushes which are connected in circuit with the fan motor.

Mounted upon the motor shaft 12 is a triction pinion 2G which engages and drives a l'riction gear 27, the latter being mounted upon a stub shaft. 28 which is carried at one end ot' an arln 2S). Also mounted upon the shaft 2S and rotatable with the friction gear 27 is a friction pinion 30 which engages and drives a friction gear 31 which is tast upon the shaft 15, so that when the parts are in the position shown in Figure 3, the countershalt 15 will loe rotated. The arm 29 forms one arm of a bell crank lever which is Apivotally mounted as shown at 32, while the other arm 33 ot this lever has pivotally and slidingly connected thereto as shown at. 34, the inner end oi' a` threaded shaft This shaft extends through the casingr 18 and operates in a nut 36 and is provided upon the its outer end with a linger piece or head 37 by means ot which it may he conveniently rotated. By rotating the shaft 35, the hell crank lever may be rocked upon its shaft 32 so as to move the gear 27 into and ont of engagement with the pinion Q6. This is clearly shown in Figures 3 and 4 of the draw ings, the last mentioned tigure illustrating the position of the gears when the counter shatt15 is idle. By this means, the shaft 15 may he operated simultaneously with the operation ot the ian, or the latter may he operated independently of the shaft 15. In addition, hy regulating the pressure ot Contact between the pinion 26 and the gear 27, the speed oi' rotation ot the shaft 15 may loe controlled. A spring 35 is mounted upon the shaft and bears against the arm 33 to yieldingly hold the gear 27 engaged with the pinion 26.

The shaft 15 is designed to operate a display device such as indicated at D in Figure 5 of the drawings, or any one of the display devices illustrated in my co-pending applications. The display device illustrated in the present application comprises radial arms 38 which extend from a hub 39. This hub is formed of insulating material and has projecting from one `tace studs 40. These studs are electrically connected by means of cond uctors 41 with lamps 42 which are carried by the radial arms 38, so that the lamps will be connected in circuit withthe fan motor.

Extending through the hub 39 is a screw 42 which is provided'with a knurled head 43 and which is adapted to extend through an opening provided in the hlocl 20 so as to engage a nut The display device is thus securely attached to the block 30 so as to resist centrifugal action, and at the same time the studs 40 which are formed by conducting material, are held in proper contact with the' contacts 22.

The invention is susceptible of various changes in its form, proportions andV minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims. Having described the invention what is claimed is s* 1. The combination with an electric fan, supported for rotation by fan motor, means operaof a display device the housing of the tively connecting the display device with tlie 'shaft of said motor to operate said device,

and means to control the speed of operation of the display devices independently of the operation of the fan.

The combination with an electric fan, of a display device supported for rotation by the housing of the fan motor, means operatively connecting the display device with the shaft of said motor to operate said device, and means to adjust said connecting means to control the speed of operation of the displayv device indcj'icndently of the operation of the fan.

3. The combination with an electric fan, of a :ountei'shaft located adjacent the shaft of the fan motor. a display device mounted upon the countershaft, gearing connecting the countershaft with the shaft of the motor, and means to regulate the speed of operation of the display device independently of the operation ot the fan.

4. The combination with an electric fan` of a casing, means to secure the casing to the housing of the fan motor, a countershaft located within and extending through the casing. a display device mounted upon the countershaft, means operatively connecting the countershaft with the shaft of the motor, and means to adjust the connecting means to control the speed of operation of the displa de- ;'ice independently of the operation o the In testimony whereof I affix my signature.
